Sound like ectopic or not? Very worried

I just don't understand... I was diagnosed with cervicitis a week ago. My hcg level was 137 on 8/20 and 214 on 8/25 then I started spotting red blood discharge and so I went to the ER later that night when my spotting had stopped and they couldn't find anything on the transvaginal ultrasound because I was too early, but my urine said I was pregnant and doctor said ultrasound looked good, was just too early and that my numbers were going up. He wasn't worried at all. So then I got home and looked at my numbers and noticed it didn't go up as much as it should have, then the next couple days it turned brown and now red again.. It's just like wiping pee... It's so weird. Like I'm on my period.. Sometimes will have discharge & when it turns brown, I wipe after I pee and it's just like as if I pooped, sorry for TMI. It keeps changing though.. I wipe it on a toilet paper.. I don't pee it out. But I'm wearing a pad now cuz a little bit went on my underwear. What's happening to me? My ovaries only hurt a little bit, but barely anything. And it goes away and comes back. Only thing that hurts the most when I'm walking lots is my lower back... But I'm also very dizzy right now and feel like I am going to puke. And I took a Clearblue test yesterday and it was darker than it was a few days ago and then I took this today and it says 2-3 weeks and last week it said 1-2 weeks, so I just don't know what's going with my body.. According to my first day of my last period I'd be 7 weeks on wednesday, but according to Clearblue today it says I'm 2-3 weeks so that makes me only 4-5 weeks ?
